Status 641 means the USPTO mailed a non-final Office Action identifying issues with your application. You typically have three months to respond with arguments, amendments, or evidence. Missing the deadline can abandon the application.

The examiner requires you to clarify your U.S. domicile address with supporting documentation or appoint a qualified U.S.-licensed attorney to represent you.
